Hi sumiprateek,

It isn't your drive, it is the partition contents my friend.

Windows Exploder (explorer) has found a file that it doesn't understand, and that doesn't trip the usual escape/error message exit mechanism.

It has been effectively left with a "divide by zero" instruction, and might be expected to take some time about it?

I had the same thing Yesterday with a GeForce video card running HDMI............... just got a lock and a grey screen............ but that was Win8 Beta It ran OK with DVI-D, but not HDMI.

I am afraid that we just have to live with these things?
